244 mg of 2-bromo-5-fluorobenzaldehyde, 1.7 g of potassium carbonate, 87 μl of water and 196 mg of [1,1′-bis(diphenylphosphino)ferrocene]palladium(II) dichloride are added to a solution of 2 g of [2-amino-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)quinazolin-4-yl]-(1,3-dihydroisoindol-2-yl)methanone in 200 ml of ethanol under argon. The mixture is heated at 120° C. for 30 min; the hot mixture is filtered through kieselguhr, and the filtrate is evaporated. The residue obtained is triturated with 2 ml of acetonitrile, and the precipitate formed is filtered off with suction.
